A hair follicle drug test<\/a> is one of the newer types of drug testing available and is quickly becoming the preferred drug testing for employers, as well as court-ordered probation testing. Hair testing allows for the detection of substances like marijuana, cocaine, opiates, barbiturates, and many other types of drugs. Hair drug testing can determine if a person has ingested drugs in the past 90 days.<\/p>\n You place an order by phone or online and you receive a donor pass to go into a local facility for hair to be collected from your head or body. Head hair is preferred.<\/p>\n Once the hair sample is collected, it is sent to one of our many certified labs for professional analysis, and review from a certified Medical Review Officer (MRO)<\/a>.<\/p>\n Negative results for a basic 5-panel hair follicle drug test are usually available within 2 to 3 days. The more complex 9 to 17 panel may take a couple days longer; positive initial test results are sent for further confirmatory GC-MS testing<\/a> which may take a few extra days.<\/p>\n","protected":false},"excerpt":{"rendered":" Hair Drug Test 7 Panel \u2013Barbiturates, benzodiazepines, cocaine, marijuana, amphetamines (methamphetamine & ecstasy), phencyclidine (PCP) and opiates (codeine, morphine & 6-MAM heroin metabolite, hydrocodone and hydromorphone, oxycodone and oxymorphone).(816062)<\/p>\n","protected":false},"featured_media":94593,"template":"","meta":{"_seopress_robots_primary_cat":"none","_relevanssi_hide_post":"","_relevanssi_hide_content":"","_relevanssi_pin_for_all":"","_relevanssi_pin_keywords":"","_relevanssi_unpin_keywords":"","_relevanssi_related_keywords":"","_relevanssi_related_include_ids":"","_relevanssi_related_exclude_ids":"","_relevanssi_related_no_append":"","_relevanssi_related_not_related":"","_relevanssi_related_posts":"","_relevanssi_noindex_reason":""},"product_cat":[17],"product_tag":[108,102,101,93,185,184,109,110,92,192,111,112,94],"acf":[],"_links":{"self":[{"href":"https:\/\/www.nationaldrugscreening.com\/wp-json\/wp\/v2\/product\/40"}],"collection":[{"href":"https:\/\/www.nationaldrugscreening.com\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.nationaldrugscreening.com\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":0,"href":"https:\/\/www.nationaldrugscreening.com\/wp-json\/wp\/v2\/product\/40\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.nationaldrugscreening.com\/wp-json\/wp\/v2\/media\/94593"}],"wp:attachment":[{"href":"https:\/\/www.nationaldrugscreening.com\/wp-json\/wp\/v2\/media?parent=40"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.nationaldrugscreening.com\/wp-json\/wp\/v2\/product_cat?post=40"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.nationaldrugscreening.com\/wp-json\/wp\/v2\/product_tag?post=40"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}How Does Hair Testing Work?<\/h2>\n
